Hueco Mundo Timeline?
I've got a question regarding the Timeline in Hueco Mundo, has Aizen been going there since long before his reveal as the traitor? He already built the whole Las noches complex and found the Espadas... but more importantly how come Nell and the guy with the hole in his face have a history going so far down? Are they both incomplete arrancar? According to my understanding the complete arrancar were created just when Aizen obtained hougyoku, but many of the Espada talk of themselves as being arrancar since WAY earlier than that
